"Two new releases will be announced this week. Both are expanded releases of two amazing works from two real Maestros, which fortunately are still with us. One is from the sixties, and the other from seventies. One of them is actually the first official edition..."

I think ToneRow when they are referring to "two real Maestros, which fortunately are still with us", without underestimating the value of the composers you posted, they're referring to 2 that are the most known among film music fans.

At least this is what I gathered. I mean, I am not sure if there would be an announcement like that for a composer that 95% of the people might not know (the majority of which are in your list)..
